ATTORNEYS upwardly in said bearing frames 18. Arranged in threaded connection with .theupper end of each bearing-frame is a vertically movable adjusting screw 21, the lower free end of which engages and determines the vertically adjusted position of said bearing-` blocks in said bearing-frames. The upper free end of each adjusting screw 21 isl provided with ahand-wheel 22 for manipulating the same. J ournaled in andl extending Abetween said bearing-blocks 19 is a shaft 23 upon which is fixed a molding roll 24, which is positioned above the receivingv end of said conveyer belt, in properly spaced vrelation therefrom. 'Connected with one end of'said shaft AA23 is a sprocket wheel 25, over which runs a driving chain26, the latter running overand being driven by a sprocket wheel 27 securedupon one end of said main driv- .inof shaft 5. Y

w Lonnected with and situated upon the upperV surfaceof said side i'ails 2 in a position slightly beyond the molding roll 24 above described, is another pair of transversely opposite vertical bearing-frames 28, in which arelarra-nged vertically adjustable bearingblocks 29. Interposed between the bottom of saidbearingframes and said bearing Ablocks are compression springs 30, which exert through their tension an upward pressure upon said bearing-blocks, tending to move the latter upwardly in said bearing frames. Arranged in threaded connect-ion with the upper end of each bearing-frame `28 is a vertically movable ad vjustingscrew 31, the lower free end of which lengagesaiidl determines the vertically adjusted position of said bearing blocks 29 in said bearing-frames 28. `The upper free end of each adjusting screw 'is provided with a hand-wheel 32'for manipulating the same. Journaled vin and extending between said bearing-blocks 29 is ashaft V33 upon which is fixed afslotter orfnotching roll 34, having a V-shaped perimeter 35, thesamebeing positioned abovethe conveyer belt in properly `spaced Vrelation thereto. Connected with thefoppositeV end of said molding roll shaft 23 is a sprocket-wheel 36 which drives Va chain 37 running over asimilar sprockety wheel V38 fixed upon saidslotter or notching Y roll lshaft 33, whereby the rotary movement l :transmitted tosaid'molding roll 24 is likewise transmitted .to said slotter or notching roll.34.` Y c Supported upon the upper ends `of said Y bearing-frames 28, so` as `torbridge Vacross from one tothe other, thusy extendinglaterally` abovethe slotter or notching roll'34, .is

a bridgeframe `39 provided vwith a centrally .disposed opening 40'inv the body thereof. The reference'character 41 indicates a suit@ -able reservoir or.V oil cup provided with a Y downwardlyl j extending`V neckr which v is passed through said opening 40. l Said neck 42 is externally threaded to receive fastening nuts 43 whereby Vthe neck is secured in supported relation to the bridge-.frame 39. A suitable wicking 44 is submerged in the oily contents of said reservoir or cup, and one end of the same passed Ydownwardly through said neck, so as to project exteriorly Y from the lower end of the latter. The lower exterior end of said wicking, is bifurcatedr as at 45 so as to'straddlexthe periphery of said slotter or notcliingroll 34. The said wicking thus maintained in contactwith the periphery of the 'slotter or notching roll 34, A

feeds down a sufficient quantityof the oily content of thereservoir or cup to maintain the periphery of the slotter or Vnotching roll thoroughly greased atall times during oper ation, so that there is'Vno-tendency Vof the roll is a 4hopper 46 beneath the open bottom ofrwhich said conveyer beltV runs. Said hopper serves to receive, the dough balls and Y,

then guide the same to proper position on the conveyerbeltto assure the proper engagement of the molding roll and slotter or notching roll therewith, as the same. are carried forward by the conveyer belt. x

As thus arranged the transverse cenveyer belt 62 is postionedfwth "its reee'ving Lend adjacent to the dseharge end of thejlengitudinal conveyer belt 15, and in a horizontal plane spaced below the plane "of the latter. The transverse yc onveye'r belt isfalso maintained againstundue sagging by means Connected with fand situated upon theup- :per surface Vof said rails 47 beyond the re- '15 62` is Va pair of opposite verticalbe'aring- 1 ceiving end of said transversejconveyerbelt frames 64, vin `which) are arranged Yvntically adjustable bearing blocks Interposed between the bottomA of said bearingeframes and said bearing g blocks are; compression springs 66v whihjexert through their'tenv sion ankupward Apressure upon thelbearing blocks, tending to. move the latter upwardly K in said bearing-frames. "Arranged in threaded connection with theljrupper end of each bearing-frame `64 is' a vertically mvable adjusting sereyvft? .which `engages and determines the vertically` adjusted position of said"bearingblocks in said bearingframes, said screwsihaving manipulating Yhand-Wheels 68 at their `upper ends. `Journaled in and ektending between'said bearingblocks V65 is "a `shaft 569 upon which is fixed a transverse slotteror'notching roll 7 0, having a V-'sha-ped perimeter 7l, the same being positioned Vabove said transverse conlic veyervbelt inproperlyspaced relation thereto. Secured upon an outwardly projecting end .ofsaid shaft 69 is a pulley 72 over which runs a crossedfdriving belt 73 driven by a pull`ey`74C nxed" uponfanouitwardly projecting lend o f said@secondr idler conveyer shaft 59, whereby rotary movement in a proper direction, is l transmitted to said transverse slotteror notehing roll '70.A Cone form 7 5 provided with axliatch or opening 7 6, which may be closed, when desired by a cover memberl77 which is fslidabl'e inV undercut guide ways `78provided in the body of said platform 75.

to assure the removal of the dough forms therefrom, and the `proper deposit `of the same `through the hatch 76, or if the latter isclosed, upon the platform 75. L

Connected with said lateral extension of the fra1`ne-work,` adjacent to the discharge `-end ofsaid transverse conveyer belt "62, is a receiving' platform S0.- A scrapermember 81 is also arranged to coperate with the discharge end of said transverse conveyer' belt to i assure the removal of the dough forms therefrom, t and the deposit of the same upon the receiving'platform 80.

VIn operationr the machinefunctions and is used as follows Firstl there is 'successively deposited in Vthe receiving vhopper 46 lumpsor balls of dou-gh of proper size and consistency ready for foriningthe rolls or buns. These lumps y or balls of dough, guided by the walls of theY Qholpper, fall through its `open bottom upon t e surface of the moving longitudinal conveyer belt-1:5. The conveyer belt l5 first carries the lump or ball or dough beneath contact with the rotating `molding -`roll 24 which flattensor rolls the "sameout into a disk like form of the required thickness. Upon emerging from beneath the molding roll the disk like form, thus produced, is carried upon the conveyer belt intojengagement with the slotter or notching roll 34," the V-shaped perimeter of which passes across its upper surface form-u ing the longitudinalslot or notch bounded on either side by the raised parallel cheeks. The conveyer` belt 15 now carries the dou-gh on to the dischargepoinu'where the scraper 7 9 removes the dough and guides 1the same to the platform 7 'wherein the opening 7 6, y 4being uncovered by withdrawing the cover vmember 77, permits the dough to drop down upon the receiving end of the transverse conveyer belt 62, upon which it is carried forward beneath and in contact with the transverse slotter or notching roll 70, the

V-fsha'ped perimeter 71 of which passes transversely across the same to form a trans- `verse or cross slot or notch intersecting the first formed slot or notch; Finally the dough thus molded land formed is discharged from the conveyer belt 62 upon the receiving platformV SOI, ready to be taken therefrom and placed in the baking pans In the event it is not desiredto cross slot 1 or notch the dough form, thecover member 77V of the platform 75 is closed over the opening 76,. so that the dough discharged from the conveyer belt l5 can not be transferred to the transverse conveyer belt 62,

but` remains on. the `platform 75,k from whence it is taken and put into the baking pans.
